Or do you think Phoenix's secondary index needs to have WAL edits that span
regions?
{quote}
WAL Edits can't span regions because our log SeqId is only guaranteed to
monotonically increase by region. Local index doesn't span edits across
regions. For transaction support, some high level support is needed but not at
the WAL level.
